well‚ you must regularly change your oil and oil filter. This involves draining the old oil‚ changing the oil filter‚ replacing the oil with clean oil‚ and disposing of the old oil. The equipment required includes four to six liters of oil‚ a socket wrench‚ a funnel‚ an oil filter‚ a car jack‚ an oil catch-pan‚ and oil rags or paper towels. The first step in changing your oil is to place the car jack under the frame of the car and lift it up high enough for you to lie underneath. This allows you

constant velocity. A simple mechanical body is said to be in equilibrium if no part of it is accelerating‚ unless it is disturbed by an outside force. Two conditions for equilibrium are that the net force acting on the object is zero‚ and the net torque acting on the object is zero. Thus‚ the following objectives were emphasized in this experiment: to determine the equilibrant force using the force table and the component method‚ to determine the unknown forces using the first condition and second

WHAT IS TORQUE? Torque is a measure of how much a force acting on an object causes that object to rotate. The object rotates about an axis‚ which we will call the pivot point‚ and will label ’O ’. We will call the force ’F ’. The distance from the pivot point to the point where the force acts is called the moment arm‚ and is denoted by ’r ’. Note that this distance‚ ’r ’‚ is also a vector‚ and points from the axis of rotation to the point where the force acts. (Refer to Figure 1 for a pictoral

INTERPRETATION OF RESULTS: This experiment circles around with the Newton’s second condition of equilibrium in rotational motion. It describes by net torque acting on a body which is zero. The ability of the body to rotate in a certain direction is varied according on how much torque is applied. To prove that‚ a beam that is subjected to two forces is balanced by adjusting the perpendicular distances. When applied force is weight‚ modification in masses added is also done. Once equilibrium is achieved

the climbing technique‚ see dyno (climbing). A dynamometer or "dyno" for short‚ is a device for measuring force‚ moment of force (torque)‚ or power. For example‚ the power produced by an engine‚ motor or other rotating prime mover can be calculated by simultaneously measuring torque and rotational speed (RPM). A dynamometer can also be used to determine the torque and power required to operate a driven machine such as a pump. In that case‚ a motoring or driving dynamometer is used. A dynamometer

temporary difference in the balance of power. This power unbalance causes a difference in torque applied to the shaft‚ which causes it to accelerate or decelerate‚ depending on the direction of the unbalance. As the rotor changes speed‚ the relative rotor angle changes. Fig. 2 shows the relationship between the rotor (torque) angle δ‚ the stator magnetomotive force (MMF) F1‚ and the rotor MMF F2. The torque angle δ is the angle between the rotor MMF F2 and the resultant of the vector addition of
